Works great at controlling phosphates. Also, works well in a media reactor as I use it with the TLF media reactor with a maxi-jet pump.

I've been using the brs standard gfo and this gfo makes a huge difference. I couldn't keep my phosphate under .06 with the standard stuff. Now I've got it down to .01 in only the first week of using this product! I'm very happy even though it's a little more money.

i really love this media, i have seen drastic changes while using this. i tends to last long than the cheaper stuff. less dust is a big plus. i must say though what until it is on sales thats when i order it.

This gfo took my phosphates from .5 to undetectable . Amazing stuff now my corals are way more colorful and polyps are fully extended. Couldn't be happier with this product.

BRS' standard gfo is amazing... but this... this takes it to another level. My square 60 gallon salt tank was fill to the bring of slimy green algae. My brother then took this stuff... put it into my two reactors i recently bought and within a week the green disappeared. After 2 months, the water has remained crystal clear. The best time to get this is during their sale which is what we did during their black friday sale. Can't go wrong. Double the power of the standard stuff no joke!

GFO that makes a differemceBy terminatoron 12/2/2013

I have used many different types of phosphate removal products and for cost, quanity and effectiveness you can't beat the high capacity version of this GFO. There are a few other products that are as effective but cost more and you get less of it. Why spend more?

This is the only practical GFO to use, hands down

Tank is looking better after only daysBy Geoon 11/20/2013

Our LFS ran out of RowaPhos and it was going 3 weeks, I tried other gfos but they didn't do it, too much dust or they would just clump and not tumble, gave the high capacity a go and my tank is already looking better. I believe I will be sticking w this from here out.

Great ProductBy MICHAELOon 9/30/2013

Very well constructed and easy to change canisters, mounting option is cool. Makes use of space and utilizes 2 separate elements for individual change, Bottom line is, it makes life much easier! If you have a need for these elements then you have a need for this item.

By using this over the regular GFO I was able to mix with the ROX carbon and fit in one reactor.
